Use docker to simply create a python container

 /root/docker_python directory structure:

.
|-- demo
|   `-- main.py
`-- docker-compose.yml

main.py content:

# coding=utf-8
# -*- coding: utf-8 -*-

if __name__ == '__main__':
    print("hello world")

docker-compose.yml contents:

version: "3"
services:
  docker_python:
    image: python:2.7.18
    container_name: py_app
    working_dir: "/root"
    restart: always
    volumes:
      - "/root/docker_python/demo:/root/demo"
    networks:
      - py_net
    stdin_open: true
    tty: true
networks:
  py_net:
    #driver: bridge

Which  stdin_open is equivalent to  run the command  -d,

which  tty is equivalent to  run the command -i

stdin_open: true
tty: true

Among them, networks can use the created network, assuming xxx is the created network

networks:
  xxx:
    external: true
